homebrew-cask: google-cloud-sdk broken

Description of issue

Not sure if this is the right place for this but the google-cloud-sdk is broken under default situations. It broke when after installing python@3.9 and is I tried reinstalling to fix and now it can’t be installed. I’m pretty sure this is because of python@3.9 being the default and linked python version and google-cloud-sdk not supporting it. I imagine it’s fixable by having a dependency on 3.8 and setting up the install to use it. Not sure about the inner workings of brew and if you can have a formulae dep in a cask?

Command that failed

brew cask install google-cloud-sdk

Updated google-cloud-sdk for python39 Issue #91744 google-cloud-sdk fails to install or work because it doesn't work with python 3.9 yet and that is the default python3 in homebrew. Please review th... — committed to xaocon/homebrew-cask by epitstickpan 4 years ago

I see same issue. I don’t know if it’s right way, but I was able to reinstall it below.

brew unlink python@3.9
brew unlink python@3.8
brew link python@3.8
brew cask install google-cloud-sdk

I think linking to 3.8 is the right way to go, just not sure about the best way to go about it. you have to force link 3.8 (at least that’s how it is for me) and there are a number of formula that expect 3.9 and I think may cause breakage if you you unlink 3.9 and force link 3.8. I think you want the install to use CLOUDSDK_PYTHON=/usr/local/opt/python@3.8/libexec/bin/python for install but what to do after that to force gcloud and the other bins using it is the questionable part. I’m not sure that if you install with the correct ENV variable it will stick with the bins. I’m guessing we’d either have to patch the scripts, which wouldn’t be too hard, or maybe make shims that are installed in the path that just set the var and call the real bins. There are some other options too but the others I can think of right now require changing the ENV for the user at all times and seems messy.

If the maintainer or a “owner” of this project can chime in on what’s normal or allowed I can probably come up with a PR. I just don’t want to get started on something that won’t have a chance of being accepted. I also don’t know how deps work between normal formula and casks.

I tried doing this:

executable: "CLOUDSDK_PYTHON=/usr/local/opt/python@3.8/libexec/bin/python google-cloud-sdk/install.sh",

…but got this error:

Error: Failure while executing; `/usr/bin/env PATH=/usr/local/bin:/usr/local/sbin:/usr/local/Homebrew/Library/Homebrew/shims/scm:/usr/bin:/bin:/usr/sbin:/sbin CLOUDSDK_PYTHON=/usr/local/opt/python@3.8/libexec/bin/python\ google-cloud-sdk/install.sh --usage-reporting false --bash-completion false --path-update false --rc-path false --quiet` exited with 127. Here's the output:
env: --usage-reporting: No such file or directory

…which means that the whole executable argument is being treated as a single path, and so cannot embed environment variables.

Trying this instead:

  installer script: {
    executable: "CLOUDSDK_PYTHON=/usr/local/opt/python@3.8/libexec/bin/python",
    args:       [
      "google-cloud-sdk/install.sh",
      "--usage-reporting", "false", "--bash-completion", "false", "--path-update", "false",
      "--rc-path", "false", "--quiet"
    ],
  }

…gives this error:

Error: Failure while executing; `/usr/bin/env PATH=/usr/local/bin:/usr/local/sbin:/usr/local/Homebrew/Library/Homebrew/shims/scm:/usr/bin:/bin:/usr/sbin:/sbin CLOUDSDK_PYTHON=/usr/local/opt/python@3.8/libexec/bin/python google-cloud-sdk/install.sh --usage-reporting false --bash-completion false --path-update false --rc-path false --quiet` exited with 127. Here's the output:
env: google-cloud-sdk/install.sh: No such file or directory

…which means env isn’t resolving the relative path when there’s another env-var arg before it, for some reason.

I don’t know enough about the cask DSL to suggest another “hacky” alternative.

But as for non-hacky ones, it seems like ScriptInstaller could/should make use of an env map if one was found in the script map argument, merging into the one it builds in https://github.com/Homebrew/brew/blob/bf7fe45e8998e56e6690347a0192c454b8cb203b/Library/Homebrew/cask/artifact/installer.rb#L41-L43 . E.g.

  installer script: {
    executable: "google-cloud-sdk/install.sh",
    args:       [
      "--usage-reporting", "false", "--bash-completion", "false", "--path-update", "false",
      "--rc-path", "false", "--quiet"
    ],
    env: {
      "CLOUDSDK_PYTHON" => "/usr/local/opt/python@3.8/libexec/bin/python"
    }
  }

Not sure if anything else would ever use it, but it seems like an obvious “should have” feature of the DSL.

Here is what I would suggest:

Add a depends_on formula: "python@3.8" to the Cask file and a caveat explaining that you will need to set the environment variable CLOUDSDK_PYTHON=/usr/local/opt/python@3.8/bin.

miccal on Oct 30, 2020

I think setting CLOUDSDK_PYTHON as an environment variable should be fine, so I think your last idea of using env would be a good way to fix this issue.

miccal on Nov 1, 2020

In the Cask file if you replace the line:

executable: "google-cloud-sdk/install.sh",

with:

executable: "CLOUDSDK_PYTHON=/usr/bin/python google-cloud-sdk/install.sh",

so that it uses the macOS version of Python 2, does that work?
